What this IPv4 multicast MAC mapping question tests

This is an easy networking fundamentals question that tests your understanding of how the internet and link layers communicate. It probes whether you know the practical mechanism by which IPv4 multicast addresses translate to Ethernet frames—knowledge essential for anyone working with low-latency market data feeds, cluster protocols, or high-performance networking code.

The question rewards familiarity with the address resolution layer and the bit-level conventions that bridge IP and MAC addressing. Rather than requiring complex calculation, it asks you to understand a standard mapping rule and why it exists.

  • IPv4 address structure and multicast ranges
  • Ethernet MAC address format and reserved address blocks
  • Address translation between network layers
  • Practical implications for network hardware filtering
